[2] In 1967, planning stages commenced for a Marmion Town Centre with 17,000 square metres (180,000 sq ft) of retail space by 1986 in the southwestern corner of the suburb to be developed by the Lands Department in conjunction with the Rural and Industries Bank.

Martin and Associates,[3] but Warwick, Karrinyup and small local centres had filled the retail need in the area and population had developed somewhat differently from original expectations, so the plan was shelved.

[4] In the Northwest corner of Duncraig is a tangle of streets named after Gilbert and Sullivan characters and personalities.

[5][6][7] Duncraig is a residential suburb, although has numerous small parks and bushland areas, and the Percy Doyle Reserve which contains a library and recreation centre.

It also contains a multipurpose sports complex including several football fields and soccer pitches, lawn bowl greens and over 20 tennis courts.

[4] Just beyond Duncraig's southern boundary is Carine Regional Open Space, a wetland reserve centred on two large swamps which is home to many rare waterbirds, frogs, turtles and other wildlife.

The space is served by walking and bicycle tracks and also offers AFL, Soccer Pitches, tennis courts and is also home to the Carine Cats baseball and teeball clubs.
